Can someone please explain why ccra and project (lines 1 and 3) return ccr and projec, respectively, while the other two examples return what I would expect, ccrb and projecs?

"ccra_Data.mdf".trimend("_Data.mdf") #1
"ccrb_Data.mdf".trimend("_Data.mdf") #2
"Project_Data.mdf".trimend("_Data.mdf") #3
"Projecs_Data.mdf".trimend("_Data.mdf") #4

Thanks!

TrimEnd accepts a char array, not a string. This is a more explicit way to write the code:

[char[]]$charArray = @('_','D','a','t','a','.','m','d','f')
"ccra_Data.mdf".TrimEnd($charArray) #1
"ccrb_Data.mdf".TrimEnd($charArray) #2
"Project_Data.mdf".TrimEnd($charArray) #3
"Projecs_Data.mdf".TrimEnd($charArray) #4

Notice the letters I bolded above are contained in the char array.

Mystery solved. Ugh.

I managed to do what I wanted using Substring and IndexOf.

Thanks!
